If you have a stock air box you will need to buy some kind of an Intake kit. My K&N works just fine.

Remove the hose between the air box and the air pump.

If you can, remove the front nose clip so you can take out the air pump resonator located next to the washer fluid reservoir. It is a cylindrical canister with a hose that goes somewhere, mine wasn't hooked up when I bought it.

Take out the canister and anything that is connected to it.

Loosen the air pump so you can take off the belt.

Take out the three, I think, bolts holding on the air pump.

Remove the air pump.

You can now take off the bracket that holds the air pump.

There you go. I would now recommend removing the ACV and Split air pipe along with getting a downpipe, if you don't already, and a straight pipe. I have heard that if you run the cats without the air pump they will clog since the do not get the appropriate air to burn everything.
